Summary

Version 0.1.1 of the "scan-for-secrets" tool was released on April 5th, 2026, designed to identify secrets within files intended for sharing. This update includes enhanced documentation detailing the various escaping schemes that the tool now scans for. Additionally, the `repr` escaping scheme was removed from the scanning process, as its functionality was already comprehensively covered by the existing `json` scheme.

Key takeaway

The `scan-for-secrets` 0.1.1 release enhances its ability to detect sensitive data in files prior to sharing. This update explicitly documents all scanned escaping schemes and refines its detection logic by removing the redundant `repr` scheme. This provides clearer, more robust secret scanning, critical for developers and security teams aiming to prevent accidental credential exposure in shared code.
